A knowledge of ionisation energies helps us understand the elements and their chemistry. The usual plots of first ionisation energies give us little insight. Apparent irregularity of first and second ionisation energies of transition metals and lanthanides can be explained in terms of the electronic configurations of the ground states. Periodicity…

Energy is a disciplinary core idea and a cross-cutting concept in the K-12 Framework for Science Education and the Next Generation Science Standards (NGSS). As numerous authors point out, the energy model in these standards emphasizes the connections between energy and systems. Using energy ideas to interpret or make sense of phenomena means…

Recognizing the relevance of energy in our lives is essential for ensuring a sustainable future. The lessons offered by education systems could exert an impact throughout the lives of people. This study conducts a review of the content of elementary-level textbooks in Mexico to describe and analyze the scope of these materials and their depth from…

Purpose: There is a great interest in developing eco-friendly operations as alternative uses of resources in the university campus, making the employment of technologies more sustainable. Practices such as energy management and efficiency initiatives have been encouraged to meet these sustainability goals. The purpose of this paper is to describe…

This article presents ideas and narratives of an experiment on the concept of energy developed for an honors seminar on energy and a mechanics course. We argue that energy is an idea best taught in an interdisciplinary manner. While most physics courses explore ideas such as mechanical energy and conservation of energy, it is imperative that a…

American adolescents consume more sugar-sweetened beverages (SSBs) than any other age group. Sports and energy drinks consumption among adolescents is higher than other SSBs. For sports drinks, there is uncertainty about their "healthiness" and also beliefs that these drinks may provide health benefits such as hydration, enhanced…

This paper outlines the result of an innovative program to develop a competency-based curriculum and a work process to engage students in energy assessment of small commercial buildings in their community. Throughout the resulting course, "Leadership in Building Energy Efficiency (LBEE)," students were trained to gather buildings'…

The study aimed to examine the effects of design-based STEM activities developed for renewable energy sources on science teacher candidates' perceptions, attitudes, and behavioral orientations. The one-group pretest-posttest design was used. The participants comprised 40 second-grade teacher candidates studying at a public university, and the…

An online survey was administered to all educators and specialists within the University of Maryland Extension to assess client-driven opportunities and priorities for energy-related programming, while in-service training evaluations were used to further assess programmatic needs. Results indicate the need for information related to energy…

At the time of the current global energy crisis energy awareness education in school is increasingly important. Textbooks directly helping and influencing learning play an important role in this, especially in the case of natural sciences. Thus, the aim of this research was to show how science textbooks help to educate energy awareness (EA).…

Energy awareness education as part of sustainability education is the joint task of schools and society as a whole. However, only teachers who themselves possess this competence can educate students in energy awareness. Accordingly, the aim of the research was to examine the energy awareness of pre-service teachers. To achieve the aim, the…

Concerns regarding students' difficulties with the concept of energy date back to the 1970s. They become particularly apparent for systems involving adenosine triphosphate (ATP), which plays a central role in maintaining the nonequilibrium state of biological systems and in driving energetically unfavorable processes. One of the most…

The Youth Strike for Climate raised important global attention to interconnected climate, energy and environmental issues -- it also compelled us to consider what we will do to address these pressing challenges. Developed through consideration of such dynamics, we propose critical energy literacy as an emerging theory that denotes understanding of…

This study examined assessment item difficulty patterns in two energy aspects, energy source/form/transfer and energy degradation/conservation, across and within science disciplines. The participant students were taking at least one college-level introductory science course. Findings showed a common pattern of item difficulties for the two energy…

In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…
